FLUID MOTOR Filed May 13, 1950 R m w M Patented Sept. 22 1931 UNITED STATES P T NT O I- f enonens FRANCIS MICHOT-DUIQONTI; or eans; Eamon FLUID oron Application filed May 13, 1930, Serial No. 452,034, and in Belgium May14, 1929.

The present invention relates to fluid motors and, more particularly, to those designed to be actuated by the wind.

One of the objects of the invention is'to provide a motor having fluid resisting surfaces of a form adapted to convert the rec-' tilinear fiow of the wind into a rotatory couple.

Another object is to provide means for regulating the action of the wind motor.

Further objects will appear in the course of the detailed description now to be given with reference to the accompanying draw-- ings, in which I v Fig. 1 is an elevation, partially in section,

of one illustrative embodiment of the in sheet metal surfaces d 9 and d g posi-- tinned symmetrically with relatlon to shaft a and formed so as to present, in section, a curve having one extremity farther from the axis of rotation than the other (the apparatus being in the position shown in Flg.

E 2), the extremity nearest said axis being substantially concentric therewith (in practice, surfaces 01 d are circular, cylindr cal quadrants fitted on one side either with a rectilinear extension 9 g or with an extension concave relatively to the central axis of the cylinder) ,and a pair of end plates 6, e having orifices f, f formed therethrough. Extensions g g may be formed integrally with surfaces 03 d or may be mounted to swlng pivotally with relation to the latter in a manner hereinafter to be described.

Assuming g and g to be integral and continuous with d and d -respectlvely and surfaces d =9 and 01 g to be rigidly attached to end-plates e, e in the manner of the blades of a water-wheel, the motor will fUHCt-IOII as follows. The wind blowing in the direction of the arrows shown in Fig. 2 strikes surface 9 and is deflected inwardly along surface 03 back onto surface d g .-thus producingafirst turning moinent on d 9 and a second on 03 9%., At the same time ele ment 9? receives the direct impact of the wind on its exterior surface and deflects-the latter outwardly. The air deflected into the space between (P, g and (Z 9 and whose force has been spent willdischarge through orifices f, f. i u

It is advisable to regulate theturning 'effect exerted by, and on surfaces 1 ,9? and d3, 9 of being integral and continuous are formed in. two, sections,.a curvedportion d 'or d concentric with shaft and rigidly. attached to plates and astraight portion 9 or g pivotallyjconnected to elements 03 or d by verticalhinges h, k positioned symmetrical.- ly, with relation to theaxis of rotation. I A

pair 10f arms. j,., j connected to each of sur faces 9 and g carries adjustable weights 2', i which exert a'force, under the centrifugal action of the motor, tending to move these surfaces towards the axis of rotation (dotted line position in -'F ig. -2),. appropriate stops being provided to limit t-he turning inovement o'f surfaces g g From theforegoing itwill be evident that if weights 2', i areproperly chosen, the wind resistance offered by extensions 9 9 will diminish with i ncreasing velocities of the motor; and excessive speeds that might deteriorate or destroyrthe apparatus, in time of storm, will be prevented; I I

To cause the. motor to begin to rotate even if it has stopped in such a osition that the action of-the wind on sur aces (F, g equiliberates that on surfacesd", g ,fa=pair of auxiliary sheet metal surfaces 10 ,70 may be provided. extending between end plates ie, 6, said auxiliary surfacesbeing positioned at equal distances between surfaces al (2 and symmetricallyhwith relation to shaft a and being formed so as to present, in section a line having one extremity farther from the axis of rotation than the other.

What I claim is 1. In a fluid motor, a fixed support, and a rotatable assembly mounted on said fixed support and comprising a rotatable supporting element, and a fluid-resisting element hav- In such a. case these surfaces-,finsteading a surface presenting, in section, a line having one extremity farther from the axis of rotation of the rotatable assembly than the other, the extremity nearest said axis of rotation being substantially in the form of a cir cular are struck ofi with the axis of rotation as a center and positioned in spaced relation to the latter;

2; A structure as defined in claim 1, in combination with a secondfiuid resisting element of like form to thatof the first fiiiidresisting element and positioned in symm etri:

cal relation thereto relatively to the axis of r rotation of'th'e rotatable assembly.

. 3. In a fluid motor, a fixed support, and a i I rotatable assembly mounted on said fixed support and comprising, a first fluid resisting element having a ortion Of its Siiifa ositioned at a constant distance from the axis of rotation of the rotatable assembly conejentric with 's aid'a'xi's, and a second fluid resisting element having a surface-movable with relation to said axis of rotation.

4:. In a fluid motor, a fixed support;-and a rotatable assembly mounted on said fixed support and comprising a rotatable supporting element, a first fluid resisting element rigidly mounted on said supporting element and having'fa surface presenting, in section, a line in the form of a circular arc struck off withthe axis of rotation as a center and lying cjoneentric with said axis, and a second fluid re isting element pi'votally supported on said rotatable supporting elementand having 'a 'plane surface.

5. A structure as defined in claim 4 in combination with a'rod connected to said second fluid resisting element and extending beyond 4 the pivotal axis thereof, and a weight mountied on said rod.

6. In a fluid motor, a fixed support, and a rotatable assembly mounted on said fixed s'upport and comprising a rotatable sup-porting element, arfirst fluid resisting ele'm'ent rigidl'y mounted on said supporting element and having a surface presenting, in section, at

least in part, a line in the form of a circular arcstruck off with the axis 'of rotation as a center and lying concentric with said axis, a second fluid resisting element pivotally supported on said supporting element, weight supporting means eonnectedto said second fluid resisting element and extending beyond the pivotal axis thereof, and a Weight mounted 'on said weight supporting means.

In testimony whereof I aiiix my signature.
